R Projects
R Projects are a super helpful feature of RStudio. They help you:
Stay organized. R Projects help in organizing your work into self-contained directories (folders), where all related scripts, data, and outputs are stored together. This organization simplifies file management and makes it easier to locate and manage files associated with your analysis or project.
Find the right files. When you open an R Project, RStudio automatically sets the working directory to the project’s directory. This is where RStudio “looks” for files. Because it’s always the Project folder, it can help avoid common issues with file paths.
Be more reproducible. By encapsulating all the files for an analysis within a single project, R Projects enhance reproducibility. You can share the entire project directory with others, and they can replicate your environment and analysis without much hassle. This is particularly important for research and collaborative work where transparency is key – i.e., for publications!
Let’s go over how to create and use an R Project!
New R Project
Let’s make an R Project so we can stay organized in the next steps. Click the new R Project button at the top left of RStudio:
In the New Project Wizard, click “New Directory”:
Click “New Project”:
Type in a name for your new folder.
Store it somewhere easy to find, such as your Desktop:
You now have a new R Project folder on your Desktop!
Make sure you add any scripts or data files to this folder as you go through your Intro to R lessons, or work on a new project. This will make sure R is able to “find” your files.
Testing out your R Project
Let’s read in some data.
read_csv() needs an argument file =.
fileis the path to your file, in quotation marks- can be path to a file on a website (URL)
- can be path in your local computer – absolute file path or relative file path
# Examples
dat <- read_csv(file = "www.someurl.com/table1.csv")
dat <- read_csv(file = "/Users/avahoffman/Downloads/Youth_Tobacco_Survey_YTS_Data.csv")
dat <- read_csv(file = "Youth_Tobacco_Survey_YTS_Data.csv")If we aren’t reading from URL, and we are Reading from your computer.. What is the “path”?
